Ehud Ahissar offers a new kind of dualism for neuroscience

Years of studying how rodents actively sense their environment through whisking has led Ehud Ahissar, professor of neuroscience at the Weizmann Institute of Science, to propose a dualistic framework for consciousness. He suggests we communicate with others (and ourselves) through a non-physical digital process. By contrast, we experience the world through a physical analog process. These two processing modes map onto complementary opposing hierarchical loops of brain circuitry.
